PHP中 copy函数 <a href="http://www.w3school.com.cn/php/func_filesystem_copy.asp" target="_blank">http://www.w3school.com.cn/php/func_filesystem_copy.asp</a> <div id="codeText" class="codeText"><ol style="margin:0 1px 0 0;padding:5px 0;" start="1" class="dp-css"><li><?php </li><li>
        echo copy("source.txt","/usr/local/apache/htdocs/class/classnotes/destination.txt"); </li><li>
?></li></ol></div> 如果成功实现复制的话 <a href="http://blog.chinaunix.net/attachment/201108/26/22666248_1314356597RRaa.jpg" target="_blank"><img src="http://blog.chinaunix.net/attachment/201108/26/22666248_1314356597RRaa.jpg" .load="imgResize(this, 650);" ;="" border="0"></a> PHP实现文件上传 is_uploaded_file()函数确定右输入参数filename知道你的文件是否使用POST方法上传。 boolean is_uploaded_file(string filename) test1.php <div id="codeText" class="codeText"><ol style="margin:0 1px 0 0;padding:5px 0;" start="1" class="dp-css"><li><form action="upload1.php" enctype="multipart/form-data" method="post"> </li><li>
     Last Name:<br /> <input type="text" name="name" value="" /><br /> </li><li>
     Class Notes:<br /> <input type="file" name="classnotes" value="" /><br /> </li><li>
     <p><input type="submit" name="submit" value="Submit Notes" /></p> </li><li>
</form></li></ol></div> upload1.php 使用is_uploaded_file()函数确定表单域指定的文件确实是通过表单上传的文件。 basename($classnotes); <div id="codeText" class="codeText"><ol style="margin:0 1px 0 0;padding:5px 0;" start="1" class="dp-css"><li><?php </li><li>
if (is_uploaded_file($_FILES['classnotes']['tmp_name'])) { </li><li>
     copy($_FILES['classnotes']['tmp_name'], </li><li>
              "/usr/local/apache/htdocs/class/classnotes/".$_FILES['classnotes']['name']); </li><li>
} else { </li><li>
     echo "Potential script abuse attempt detected."; </li><li>
} </li><li>
?></li></ol></div> <a href="http://blog.chinaunix.net/attachment/201108/26/22666248_13143568422447.jpg" target="_blank"><img src="http://blog.chinaunix.net/attachment/201108/26/22666248_13143568422447.jpg" .load="imgResize(this, 650);" ;="" border="0"></a> <a href="http://blog.chinaunix.net/attachment/201108/26/22666248_1314356848n4W3.jpg" target="_blank"><img src="http://blog.chinaunix.net/attachment/201108/26/22666248_1314356848n4W3.jpg" .load="imgResize(this, 650);" ;="" border="0"></a> 2.移动上传文件      move_uploaded_file(string filename, string destination); 也可以实现文件上传 upload1.php <div id="codeText" class="codeText"><ol style="margin:0 1px 0 0;padding:5px 0;" start="1" class="dp-css"><li><?php </li><li>
//if (is_uploaded_file($_FILES['classnotes']['tmp_name'])) { </li><li>
    // copy($_FILES['classnotes']['tmp_name'], </li><li>
     // "/usr/local/apache/htdocs/class/classnotes/".$_FILES['classnotes']['name']); </li><li>
    move_uploaded_file($_FILES['classnotes']['tmp_name'], </li><li>
             "/usr/local/apache/htdocs/class/classnotes/".$_FILES['classnotes']['name']); </li><li>
//} else { </li><li>
    // echo "Potential script abuse attempt detected."; </li><li>
//} </li><li>
?></li></ol></div>
